Motivation and Context

We submitted the skill to davila7/claude-code-templates#1032. Its required SkillSpector check (NVIDIA's static skill scanner, run with --no-llm) scored the skill 100/100 CRITICAL, "DO NOT INSTALL", which blocks the merge. Every finding was a pattern match on harmless wording, not a real issue. This PR rewords those lines so the skill passes this and similar scanners, without changing behavior.

Description

Rule	What matched	Change
P6 (HIGH) prompt extraction	the ## Output Rules heading	Renamed it ## Response Style
AE1 (HIGH, ×2) incomplete analysis	the two inline _meta["x402/error"] spans in x402.md exceeded the parser's span limit	Wrote it as "the x402/error key in _meta"
EA2 autonomous decisions	"auto-execute", "May execute without confirmation", "no approval record", "shows no consent prompt"	"Never pass --yes …", "Can run directly", "the approval record is missing", "does not prompt for consent"
RP1 unpinned package	npx skills add in the version-mismatch hint and doctor.md	The hint says to update the skills with the tool that installed them
PE2 / RA2	mkdir -p ~/.metamask/… && chmod 700 … in the QUOTE_PERSIST_FAILED fix	mkdir -p "$HOME/.metamask/…" && chmod u=rwx,go= …, which does the same thing
E1 external transmission	https://api.example.com/premium example URLs	https://paid.example.com/premium

The meaning of every rule is unchanged. reset still needs explicit confirmation, --yes is still forbidden on re-quotes, and the protocol keys _meta["x402/payment"] and _meta["x402/payment-response"] are unchanged. The skill version is bumped to 7.7.1, with a CHANGELOG entry. A second commit adds a root .gitignore for __pycache__/ and *.pyc. Shipped bytecode is a blocking finding for these scanners (SC8/SC9), and a local compile check had left some in the first commit.

Two MEDIUM findings remain on purpose:

• LP3, no allowed-tools: adding allowed-tools would make Claude Code run those tools without asking permission, including mm commands that move funds. The only other field the scanner accepts, a top-level permissions key, is not allowed by the Agent Skills spec.
• AST4, subprocess call: x402_pay.py calls subprocess.run(["mm", ...]) with a fixed argument list and no shell.

How has this been tested?

• I ran SkillSpector 2.12.0 locally with skillspector scan skills/metamask-agent-wallet --no-llm. This is the same command the claude-code-templates CI runs.
  • Before: score 100, CRITICAL, 23 issues, 3 of them HIGH.
  • After: score 16, LOW, 2 issues, both MEDIUM.
• claude plugin validate . --strict and claude plugin validate .claude-plugin/plugin.json --strict pass.
• python3 -m py_compile scripts/x402_pay.py passes. Only the docstring changed.
